Neurilemmomas are benign tumors of the nerve sheaths. They are usually painless and are most common in the upper extremities. Pathologically, neurilemmoma is encapsulated and made up of organized element: the Antoni A cells, the Antoni B cells and the Verocay bodies. According to Stout, neurilemmomas never become malignant. Two cases of neurilemmoma of tibial nerve and One case of neurilemmoma of lateral antebrachial cutaneous nerve are presented with a review of the literature. Tumors were enucleated and confirmed by pathological examination.

Malignant gastric lymphoma is an uncommon but important lesion with a more favorable prognosis than that ofgastric carcinoma. A total of 16 cases of gastric malignant lymphoma examined during a period from Jan. 1980 toSept. 1983 at Seoul National University Hospital were subjected to the radiological and pathologic correlations.In all cases, the diagnosis was established by histopathology of the resected specimens (9 cases) or endoscopicbiopsy specimesn ( 7 cases). Based on the comparative study of upper G-I series and macroscopic findings of thesurgically resected specimen, the authors investigated the reliable radiographic findings which can be valuable indifferentiation of gastric lymphoma from other gastric lesions, especailly carcinoma, and suggested the followingdiagnostic criteria for the malignant lymphoma of the stomach. 1. Discrete multiple polypoid lesions with orwithout central umbilication. 2. Geographic ulcer, deviated from center of the mass. 3. Irregular thickness ofelevated rim of the mass. 4. Diffuse giant gastric rugae. 5. Giant gastric rugae, mixed with other lesion.

Dieulafoys lesion consists of abnormally large gastric submucosal artery which ruptures into the stomach causing massive or recurrent intragikstric bleeding. The lesion is very small and easily overlooked even at laparatomy and aan only be correctly diagnosed by endoscopy or arteriography if the patient is actively bleeding. Three patients who were admitted with bleeding of upper gastrointestinal tract and eventually diagnosed as having Dieulafoys lesions were analysed. All were men with age range of 44 to 55 years. All patient were asymptomatic before presenting with hematemesis. Two of the three patients had had history of upper Gl bleeding. One patient used analgesics daily for ureteral colic and two patient drank alcohol excessively. Gastroscopy was performed during the bleeding episode in all three patients. Dieulafoy's lesion was seen in all three cases and in the second case, there was concomittent diffuse petechia in the whole stomach. The lesion was situated on the posterior wall of upper body in one, on anterior wall of upper body in another, lesser curvature side of gastric fundus in the other case. All three patient underwent laparotomy for persistent bleeding and the lesion was suture ligated only in two patients while in one patient vagotomy and pyloroplasty was added. Resection biopsy was performed in two cases and both revealed only normal gastric mucosa. All patients discharged after complete recover.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

PURPOSE: To assess the characteristic features of MR imaging in the diagnosis of spinal tuberculosis. MATERIALS AND METHODS: We retrospectively reviewed MR imaging of 27 cases with pathologically-proven spinal tuberculosis and analyzed the MR findings including the extent of the lesions on non-contrast T1, proton density, and T2*VI, and the specific contrast enhancement patterns of the lesion on Gd-DTPA enhnced TIWI. RESULTS: The inflammatory lesions showed low signal intensity on T1WI in 25 patients(93%) and high signal intensity on T2*gradient echo image in 25 patients(93%). Bone destruction was noted in 15 patients(55%), disc-space narrowing in 21 patients(77%), paravertebral abscess in 16 patients(59%), subligamentous extension in 23 patients(85%), kyphosis in 8 patients(29%), and spinal canal narrowing in 19 patients(70%). After Gd-DTPA was administrated, rim-enhancement was noted in all patients(100%). CONCLUSION: We conclude that MR imaging is an excellent imaging modality for establishing the diagnosis of spinal tuberculosis as well as delineating the extent of soft tissue involvement. Characteristic peripheral rim enhancement after injection of Gd-DTPA may provide rather specific diagnosis in spinal tuberculosis.

Testicular teratomas are germ cell neoplasms that consist of tissue derived from ectoderm, mesoderm and endoderm in various stages of maturation. The teratomas are subclassified into mature teratoma, immature teratoma, and malignant teratoma. depending on the appearance and maturity of the various components. Prognosis is directly related to maturity of the tissue. Recently we experienced two cases of testicular teratoma, so we report these two cases of testicular teratoma with review of literature.

Infected nonunion of the long bone, while less common today than in the past, continues to challenge orthopaedic surgeons. Various treatment methods including current techniques of internal fixation, bone graft, electrical stimulation and external fixation have been tried, but results are not always satisfactory. Authors reported successful treatment of infected nonunion by rigid internal fixation with one plate and autogenous bone graft in previous volumes 1989. Recently we adopted dual plate method, by which we overcame a greater amount of bone defect and obtained more rigid internal fixation. We have treated 14 cases of infected nonunion with this method from Oct. 1992 to Oct. 1994, and the results are as follows; 1. Tibia fractures were 9 cases, and femur fractures were 5 cases. 2. Six cases showed large bone defect. The average bone defect was 4.5cm in length and we could overcome it by Dual plate method and autogenous bone graft. 3. Six cases which showed large bone defect were united in average 5 months. 4. In remaining 8 cases, union was obtained in average 3 months.

PURPOSE: Testicular microlithiasis (TM) is an uncommon pathologic condition that is commonly diagnosed by scrotal ultrasonography. Indirect evidence suggests that this syndrome may be associated with an increased risk of testicular malignancy and infertility. MATERIALS AND METHODS: A total of 1,439 patients undergoing scrotal ultrasound during a 6-year, 5-month period (January 2003 to May 2009) were retrospectively reviewed. Any possible association of TM with pathologic findings was assessed. Among patients with TM, further grading of TM with testicular cancer and semen analysis of the infertile group with TM were also performed. RESULTS: TM was diagnosed in 87 patients (6.0%) out of a total of 1,439. Of all established pathologic entities, only testicular malignancy and infertility were meaningfully associated with TM. There was no significant difference in the prevalence of testicular cancer between each grade. Seminal profiles (sperm count, motility, morphology, and white blood cell count) were not found to be statistically different between infertile men with and without TM. CONCLUSIONS: The prevalence of TM in symptomatic men was found to be 6.0% with significant co-occurrence of TM, testicular cancer, and infertility. Further grading of TM does not seem to be essential with regard to the detection of patients with testicular cancer and TM. TM showed no significant effect on the seminal profiles of infertile men.
